Abstract:
Objective To study the changes of plasma brain natriuretic peptide(BNP)level in patients with atrial fibrillation(AF),and explore the relationship between plasma level of BNP and paroxysmal AF,persistent AF,rheumatic AF and non-rheumatic AF.Methods In total,158 outpatients and inpatients diagnosed as heart diseases were selected from the Affiliated Hospital of Inner Mongolia Medical College during October 2005 to January 2007,83 with AF and 75 without AF.Their cardiac function Was evaluated according to the classification system of the New York Heart Association(NYHA)in the United States.Plasma level of BNP was measured with bi-monoclonal antibody microparticulate enzyme immunoassay(MEIA).Results Plasma BNP level was significantly higher in AF group[(112±75)ng/L]than that in non-AF group[(39±26)ng/L,P＜0.05]with same ventricular function.No significant difference in plasma level of BNP between the groups with paroxysmal AF[(113±84)ng/L]and with persistent AF[(110±69)ng/L]was found.Plasma level of BNP Was(84±73)ng/L in the group with rheumatic valvular AF,not significantly different from that in non-valvular AF[(117±76)ng/L,P＞0.05].Conclusion Plasma BNP level is higher in AF group than that in non-AF group,but no significant difference in plasma BNP level between patients with paroxysmal AF,persistent AF,rheumatic valvular AF and non-rheumatic AF,under same ventricular function,was found.
